CUFF-BUTTON.

SPECIFICATION forming part of Letters Patent No. 376,282, dated January 10, 1888.

Application filed May 11, 1887. Serial No. 237,797. (No model.)

To all whom, it may concern-.-

Be it known that I, FREDERICK F. BIoREN, a citizen of the United States, residing at Newark, in the county'of Essex and State of New Jersey, have invented certain new and useful Improvements in Cuff-Buttons; and I do hereby declare the following to be-a full, clear, and

exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In said drawings, Figure 1 represents an elevation of a cut'fbutton embodying my improvements. Fig. 2 is a section of the same through line X, and Figs, 3, 4, 5, and 6 represent detail views.

The object of this invention is to render the use of solder entirely unnecessary, to lessen in Figs. 1, 2, and 4, and having the central portion thereof formed into a cam, A' which is arranged to bear against a spring, B, inclosed in the back to hold said back in position on a line with the post, or at right angles thereto, as indicated in the drawings. Said post passes through a back plate, 0, of peculiar construction, the form of which is shown in Figs. 2 and 3. On the inside ofthe said back plate is formed a depression, D, for thereception of oneend of said spring B, and serves to hold the latter in position and prevent ac cidental displacement thereof. A further depression, D, is also formed in the central portion of said back plate to provide a space for the free working'of said cam and spring, and

a part of the stock is cutaway, leaving a central tongue, E, which-is formed into a loop or eye, E, through which said post is passed, and which forms a portion of the bearings of said post. The portion of stock which is cutaway,

as above stated, forms in said patch a slot, S,

upon each side of said tongue and eye, in

which the arms of said post work when the back is turned or adjusted in the'different positions above referred to in relation to said post, as will be understood by reference to said Figs. 2 and 3.

The flat spring above described, against which the cam portion of the post works after the post has been slipped into its place, is laid in the recess and across said cam, and is held in place by a binding-ring, F, the circumference of which is the same as that of the back plate, the object of said ring being to aid in binding and holding said spring firmly in its seat after the shoe G has been fastened in position. Said shoe is struck up from thin sheet metal, and is somewhat larger in circumference than the back plate and ring above referred to, and is secured in position by bending the outer rim thereof over and around the edge of the back plate and compressingit firmly thereto, thereby holding the several parts firmly in place, no solder whatever being used in the construction and binding together of the several parts referred to.

It will be noticed that the shape of the shoe is eoncavo-convex at the center, thereby leaving ample space between it and the back plate for the working of the cam and spring, as will be understood.

It will also be observed that the recess formed on the inside of the back plate for the reception of the spring does not make a corresponding projection on the outside, but leaves the same perfectly smooth.

In the construction of a less expensive button the binding-ring may be dispensed with, if desired, by allowing the spring to extend entirely across the back plate and be held in place by the shoe. Said ring, however, prevents the spring from wearing the inside of the shoe,'and also gives additional elasticity to the spring.

Having thus described the invention, what I claim as new is- 1. In a cuff-button, the combination,with the back and front thereof, of a post formed from a single or continuous piece of wire and having a cam, A, at the center thereof, and a back plate having a tongue, E, slots S S, and

ICO

depression D, and a spring, said parts being combined and arranged to operate substantially as and for the purposes set forth.

2. In a cuff-button, the combination, with the post thereof, of a back plate, as 0, provided with a depression to receive the end of aspring, a central depression, D, slots, as S, and a central tongue and eye, as E and E, a spring, as B, and a shoe, as G, said parts being arranged and held in their respective relations to each other by the outer ring of said shoe being bent over and compressed upon said back plate, and arranged to operate substantially as and for the purposes set forth.
